- Summary
- We perform an amplitude analysis of B{sup ±} → {var_phi}(1020)K*(892){sup ±} decay with a sample of about 384 million B{bar B} pairs recorded with the BABAR detector. Overall, twelve parameters are measured, including the fractions of longitudinal f{sub L} and parity-odd transverse f{sub ⊥} amplitudes, branching fraction, strong phases, and six parameters sensitive to CP-violation. We use the dependence on the Kπ invariant mass of the interference between the J{sup P} = 1⁻ and 0⁺ Kπ components to resolve the discrete ambiguity in the determination of the strong and weak phases. Our measurements of f{sub L} = 0.49 ± 0.05 ± 0.03, f{sub ⊥} = 0.21 ± 0.05 ± 0.02, and the strong phases point to the presence of a substantial helicity-plus amplitude from a presently unknown source.
